Compatibility ntawmpolycarboxylate superplasticizernrog rau lwm yam khoom xyaw

polycarboxylate superplasticizerthiab ntau superplasticizers tsis tuaj yeem sib xyaw thiab sib xyaw ua ke hauv ib qho kev faib ua ke xws li naphthalene thiab aliphatic superplasticizers. Piv txwv li, qhov tsis zoo ntawm cov yas slump tuav yog qhov loj tshaj thaum polycarboxylic acid thiab naphthalene water reducer yog compounded, thiab yuav tsum tau them nyiaj tshwj xeeb. Qhov no kuj tau ua rau ntau lub tuam txhab polycarboxylate dej reducer los ua ke cov niam dej cawv nrog ntau yam haujlwm tshwj xeeb xws li slump tuav thiab lub zog thaum ntxov kom hloov mus rau cov kev xav tau ntawm kev tsim vaj tse nyob rau lub caij sib txawv, cov ntaub ntawv thiab kev sib xyaw ua ke, thiab thaum kawg ua tiav cov txiaj ntsig zoo. Txawm li cas los xij, kev sib xyaw ua ke thiab siv tswv yim ntawm niam cawv yuav tsum tau siv lub sijhawm, thiab ib hom cawv niam tsis tuaj yeem daws tau ntau yam teeb meem hauv engineering daim ntawv thov ntawm superplasticizers. Nws yog ib qho tsim nyog ntxiv rau daim ntawv thov ntawmpolycarboxylate superplasticizer, thiab nws yog ib qho tseem ceeb heev los daws cov teeb meem kev lag luam uas tau ntsib los ntawm qhov chaw engineering los ntawm cov yam ntxwv ntawm niam cawv thiab lub cev sib xyaw ua ke ntawm cov khoom me me. Nws raug nquahu kom siv covpolycarboxylate superplasticizerua ke nrog lwm cov khoom. Nco ntsoov xyuas kom meej tias cov nyhuv ntawm kev sib xyaw ua ke thiab qhov cuam tshuam tiag tiag ntawm cov pob zeb los ntawm kev sim, thiab tom qab ntawd txiav txim seb qhovpolycarboxylate superplasticizertuaj yeem ua ke nrog lwm cov khoom.

Cia mildew teeb meem ntawmpolycarboxylate superplasticizer

Thaum lubpolycarboxylate superplasticizeryog khaws cia nyob rau hauv lub caij ntuj sov kub nyob rau hauv lub caij ntuj sov, mildew phenomena xws li tso tawm cov ntxhiab tsw phem, bulging ntawm cov ntim ntim ntim, cov floating me ntsis ntawm cov kua nto nyob rau hauv lub qhib cia tank, thiab cov strip-zoo li tus floating khoom feem ntau tshwm sim. Lub ntsiab yog vim li cas tag nrho cov txheej txheem ntawmpolycarboxylate superplasticizerlos ntawm kev tsim khoom mus rau daim ntawv thov thiab kev noj yog khaws cia hauv lub xeev cov kab mob hauv lub cev, thaum uas siv cov khoom siv retarding xws li qab zib thiab hydroxycarboxylates muab cov kab mob. Cov as-ham zoo, nyob rau hauv ib puag ncig ntawm qhov kub thiab av noo thiab nruab nrab pH, tus naj npawb ntawm fungi nce exponentially. Tom qab cov fungi tuag, ib tug loj tus naj npawb ntawm corpses tshuav, uas yog lub hauv paus ua rau mildew ntawmpolycarboxylate superplasticizer. Yog li ntawd, cov khoom xyaw active nyob rau hauv mildewedpolycarboxylate superplasticizertsis cuam tshuam loj heev, thiab daim ntawv thov kev ua tau zoo yog ruaj khov.

Cov kab mob mildewedpolycarboxylate superplasticizermuaj qhov tsis hnov ​​tsw zoo thiab ua npuas ncauj ntau rau ntawm qhov chaw, uas tsis yog qhov tsim nyog rau kev noj qab haus huv ntawm cov neeg ua haujlwm thiab kev ntsuas qhov tseeb ntawm superplasticizer. Nws yog ib qho tsim nyog yuav tsum tau siv cov kev ntsuas los tiv thaiv nws. Ntawm lawv, txoj hauv kev zoo tshaj plaws yog sib xyaw cov kab mob bactericides kom ua tiav cov txiaj ntsig ntawm bacteriostasis thiab kom tsis muaj menyuam. Nyob rau tib lub sijhawm, cov txheej txheem xws li kho cov pH ntawm cov dej txo tus neeg sawv cev kom tsis muaj qhov nruab nrab (pH≤3. lossis pH> 9.0) thiab hloov cov hom retarder kuj siv tau.
